From most energy efficient to least energy efficient:
LED bulbs (relativly new)
Fluorescent bulbs (normal "energy savings" bulbs)
Halogen (used for high intensity lighting)
Incandescent bulbs (regular bulbs)
Energy efficient light bulbs are bulbs that convert a higher percentage of electical power into light. All bulbs also create waste heat, where energy is radiated as infrared. The less efficient bulbs tend to be "hotter" because of the amount of power "wasted" this way.
energy efficient light bulbs work by trapping excess heat to make more light
Energy saving light bulbs are more efficient than tungsten filament bulbs by a factor of 4 or 5 times.
They are called CFL bulbs.
If you are looking to use the new energy efficient light bulbs on a light dimmer you will need to buy specially made dimmable CFLs. Not all energy efficient light bulbs are compatible with dimmers so be sure to check the packaging for information.
Energy efficient light bulb saves half of energy consumed by a regular bulb, although it has a lower range light compare to the high energy consumer bulbs.
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
Compact fluorescent light bulbs are pretty energy efficient and are energy star rated.
Yes, non energy efficient bulbs like the incandescents waste around 90% of there energy in the form of heat. LEDs and CFLs don't even come close.
There is actually no energy efficient light bulbs in a way to interpret in physical determination. Energy efficient means less Watts required per hour compared to non energy efficient.
comparing to the traditional light bulbs energy efficient fluorescent light bulbs uses 25% to 75% energy and saves money also and it lasts up to 3 to 25 times long so there is no need to replace energy efficient fluorescent light bulbs often.
Energy efficient light bulbs can be easily recognized, as they are each given an "ENERGY STAR" label. They can be purchased at a wide variety of retail locations, including Walmart, Target, Home Depot, or Lowe's.
fluorescent light bulbs are much more efficient than incandescent light bulbs
no not at all very expensive
There are many places a person can buy energy efficient light bulbs. Some of the best places to buy these bulbs would be Home Hardware, Canadian Tire, Home Depot and Walmart.
they are more energy efficient cause they have less electricity
Normal incandescent bulbs produce a lot of heat as well as light, so are not so efficient as low energy bulbs which can give the same light but consume much less electricity
LED light bulbs are energy efficient, environment friendly, and provide huge electricity savings.
No light bulbs actually save energy, they use it to produce light. However energy efficient bulbs use less energy than the ordinary incandescent type. To my mind describing them as energy saving is wrong, they should be described as "lower energy" bulbs.
old fashioned light bulbs did nothing to the environment but the new energy efficient bulbs contain mercury which is bad for anything that comes in contact with it.
Not always. They can, but using energy-efficient light bulbs is the best guarentee to be able to save energy, and still have plenty of energy and light produced.
Some of the most well known and highly rated energy efficient light bulbs are made by NanoLight, EcoSmart, Philips, and Chevron. These can be found at any local Home Depot.
Energy efficient incandescent light bulbs can be purchased from most lighting stores and major supermarkets. They can also be purchased online at places like Home Depot, Amazon and Earth Easy.
Yes. Conventional (filement based) light bulbs are very inefficient converters of electrical energy to light - around 2% efficiency. So compared with "low energy" bulbs, which are around 8% efficient, they are wasteful.
LED bulbs, or Light Emitting Diode bulbs are far more efficient at turning energy into light than fluorescent bulbs. They are the most energy efficient bulbs available today and last much longer than any other bulbs. Although very expensive, the price is expected to come down over time.
Lose less energy as heat.
